Abstract: | Summary The flexibility of process scale high performance liquid chromatography is demonstrated by three examples of reversed-phase separations (a) a standard purification (b) isolation of trace compounds, and (c) recovery from crystallisation mother liquors. It was shown that a material, thought to be acceptably pure, contained a toxic impurity, and a remaining impurity, a previously unseen component of potential therapeutic interest. Favourable cost data were indicated for example (3). This work was conducted in the Chemical Technology Unit, University of Manchester Institute of Science and Technology, PO Box 88, Manchester M6O 1OD, UK. |
